NHibernate.PropertyValueException : not-null property references a null or transient
- by frosty
I am getting the following exception.
NHibernate.PropertyValueException : not-null property references a null or transient
Here are my mapping files.
Product
<class name="Product" table="Products">
<id name="Id" type="Int32" column="Id" unsaved-value="0">
<generator class="identity"/>
</id>
<set name="PriceBreaks" table="PriceBreaks" generic="true" cascade="all" inverse="true" >
<key column="ProductId" />
<one-to-many class="EStore.Domain.Model.PriceBreak, EStore.Domain" />
</set>
</class>
Price Breaks
<class name="PriceBreak" table="PriceBreaks">
<id name="Id" type="Int32" column="Id" unsaved-value="0">
<generator class="identity"/>
</id>
<property name="ProductId" column="ProductId" type="Int32" not-null="true" />
<many-to-one name="Product" column="ProductId" not-null="true" cascade="all" class="EStore.Domain.Model.Product, EStore.Domain" />
</class>
I get the exception on the following method
[Test]
public void Can_Add_Price_Break()
{
IPriceBreakRepository repo = new PriceBreakRepository();
var priceBreak = new PriceBreak();
priceBreak.ProductId = 19;
repo.Add(priceBreak);
Assert.Greater(priceBreak.Id, 0);
}
